Answer 1

The Get-Hotfix cmdlet returns the same results as running "wmic qfe" from the command line. Both use WMI, and only include update made through the Component Based Servicing. get-hotfix-not-returning-all-installed-kbs.html

To get the Windows Update or MSI stuff you need the code you showed in your 1st three lines of the code sample. To get all the updates, just change the value you're looking for to "*".

Hello Rich,

this was my solution
Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall*| Where-Object displayname -like "KB5004779"
